You can detach a texture from a material property, model, or Layered texture. You can also choose to detach a texture from multiple assets at once. 
To detach a texture from multiple objects:
-  Expand the Textures folder in the Scene browser. 
 
- Right-click the texture you want to detach. 
 
- Select Detach x From All Objects, where x is the name of the texture. 
The texture is detached from all objects. Objects include models or Layered textures. 
  
To detach a texture from a model:
-  Expand the Scene folder in the Scene browser. 
 
- Double-click the model from which you want to detach a texture. For example, a Shadow Map would be a texture type that is directly applied to a model. 
 
- Right-click on the texture in the model folder, and select Detach x From y, where x is the name of the texture and y is the name of the model. 
The texture is no longer attached to the model, but is still present in the scene. 
  
To detach a texture from a material property:
-  Expand the Materials folder in the Scene browser. 
 
- Double-click the material to display its Material settings. 
 
- In the Material settings, right-click the name of the texture associated to a material property, such as Diffuse. 
Note: In one material, the same texture may be attached to multiple properties. Detaching the texture from one property does not detach it from the other properties. 
  
- Select Detach from the menu. 
The texture is detached from the material property, but it is still present in the scene. 
  
To detach a texture from a Layered Texture:
-  Expand the Textures folder in the Scene browser, then double-click the Layered texture. 
 
- Click the Layer Settings tab to display the Layer Editor. 
 
- Select a texture from the list of layers in the Layer Editor. 
 
- Click the Remove button. 
The texture is detached from the Layered texture, but is still present in the scene.
